March 2026: TensorZero monthly summary for tensorzero/tensorzero. Delivered API Key Expiration Management, introducing an expiration mechanism for API keys with UI components for selecting expiration dates and backend logic to enforce expiration. Implemented a database change by adding an expires column to support accurate expiry checks. Addressed a critical bug by ensuring expired keys are properly handled and blocked. The work strengthens API security, governance, and user control, reducing the risk of stale credentials and improving policy compliance. Technologies demonstrated include frontend UI for date selection, backend expiration enforcement, and database schema changes, with cross-functional collaboration (co-authored by Gabriel Bianconi).

February 2026: Delivered a foundational Model Listing and Discovery feature for 0xPlaygrounds/rig, establishing a trait-based API surface for discovering provider models and laying groundwork for cross-provider model marketplaces. The changes introduce ModelListingClient, ModelLister traits, and core types (Model, ModelList, ModelListingError) to standardize model data and error handling, while removing the total field from ModelList to reduce payloads and improve streaming efficiency. This work tightens integration points with provider capabilities and accelerates scalable model discovery across ecosystems.
